So sometimes things are ahead and sometimes they are behind;Sometimes breathing is hard, sometimes it comes easily;Sometimes there is strength and sometimes weakness;Sometimes one is up and sometimes down.Therefore the sage avoids extremes, excesses, and complacency.

It is far better to dare mighty things to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much because they live in the gray twilight that knows not victory nor defeat.

Theodore Roosevelt (1858 - 1919)

Enduringly successful people, many of whom live a life that’s a gift to the world, don’t raise balance as a major issue—not because they had it masterfully handled, but because they were all busy doing what mattered to them.
